Abstract

A reactor includes: a coil; a magnetic core arranged inside of the wound portion and an outer core portion arranged outside of the wound portion; and a resin molded portion. An interval between the wound portion and the inner core portion differs in a peripheral direction of the wound portion. The reactor includes an electrically insulating material that is interposed in a location at which the interval is the narrowest, and a thick portion that is interposed in a location at which the interval is the widest and forms a portion of the inner resin portion. The proportion of the interval of the narrowest location with respect to the thermal conductivity is less than the proportion of the interval with respect to the thermal conductivity.
